Highlighting breaksbrowsing

Hi
I just installed notepad++ to new windows 10 home 64bit machine and then put the userDefineLang.xml to the settings directory to have custom syntax highlighting like before.
But what happens now sometimes is that the highlighting breaks and all the text gets gray like there’s quotation mark open or green like comment open.
Then I have to restart notepad++ to get the highlighting working again

Still haven’t been able to fix this. I tried reinstalling notepad++ but it didn’t help. Maybe it’s just the user defined language that doesn’t work but it used to work.
Does anyone have ideas what to try?

I don’t have the information right now which version it was because I have new PC now but
I believe it was latest. I can’t also remember anymore did I download the UDL file or create it my self. I think I created it and took command list from another file.

Here’s link to the UDL file if some one wants to take a look. It’s for arma .sqf files
